Suggest the factors for which organisms are competing in a given habitat.
Plants often compete with each other for light and space, and for water and nutrients from the soil.
1 of 27
Suggest how organisms are adapted to the conditions in which they live in.
Organisms have features which enable them to survive in the conditions they normally live in.
2 of 27
Define an ecosystem.
An ecosystem is the interaction between a community of living organisms and and their environment.
3 of 27
Define independance.
Species relying on one another in some way in order to survive.
4 of 27
Explain how organisms are adapted to live in their natural environment.
Animal and plants are adapted for survival in conditions where tehy normally live e.g deserts, the Artic.
5 of 27
Define an extremophile.
A microorganism, especially an archaen that lives in conditions of extreme temperature e.g. acidity.
6 of 27
Define a producer.
Producers are organisms which make their own organic nutrients usually using energy from sunlight.
7 of 27
Define a primary consumer.
The name given to a consumer that eats a producer known as a herbivore.
8 of 27
Define a tertiary consumer.
An organism which obtains its energy by eating the secondary consumer.
9 of 27
Define a secondary consumer.
An organism which obtains its energy by eating the primary consumer.
10 of 27
Define biodiversity.
The range of animals living in a given area.
11 of 27
Recall the water cycle.
Water evaporates in the air, Water vapour condenses in the clouds,Water falls as precipitation and Water returns into the sea.
12 of 27
Recall the carbon cycle.
Photosythesis,Feeding,Respiration,Fossilation,Combustion,Excretion,Egestion and Decomposition.
13 of 27
Explain the role of microorganisms in cycling materials in an ecosystem.
Microorganisms help return minerals and nutrients back to the environment so that the materials can then be used by other organisms.
14 of 27
State the benefit of having a great biodiversity.
Ecosystems having higher biodiversity makes fewer species relying one each other for food,shelter and maintaining their environment. They can adjust to changes as well.
15 of 27
How are human activities affecting biodiversity.
We are slowly realising that the future of our species on Earth depends on maintaining biodiversity. Activities which create air and water pollution reduce biodiversity in ecosystems.
16 of 27
State some environmental changes.
Climate change and global warming.
17 of 27
Describe global warming.
A long term rise in the overall temperature of the Earth and is caused by increased levels of carbon dioxide,CFCS and other pollutants.
18 of 27
How are humans reducing the effects of global warming.
Planting more trees to absorb more carbon dioxide, burning fewer fossil fuels and being more energy efficient.
19 of 27
List consequences of deforestation.
Forest habitats are destroyed,soil erosion increases and air pollution
20 of 27
Explain the destruction of peat bogs.
For many years peats was removed from bogs for gardeners to add to their soil or to burn as a fuel. Peat bogs take a long time to to form and is a non-renewable resource.

Construct food chains.
Savanna grass-locust-meerkat-jackal-lion
22 of 27
Define a quadrat.
A square used in ecology.
23 of 27
List abiotic factors
light intensity,temperature,soil PH,and soil moisture.
24 of 27
List biotic factors.
competition,grazing,disease,food availibility and predation.
25 of 27
State why large scale deforestation has occured in tropic rainforests.
Tropical rainforests contain natural resources, population is increasing,and needing space to farm.
26 of 27
Biological consequences of deforestation.
Biodiversity will decrease,climate to become more extreme,landslides,soil erosion and humidity.
